3M Wetordry Paper Sheet 431Q features extra-fast cutting silicon carbide on a strong C-weight, waterproof paper backing to provide superior finishing for both wet and dry applications on a variety of substrates, including paint, primer, gel coat, metal, and wood.

Used dry or with water, 3M Wetordry Paper Sheets enable the user to rinse areas of the workpiece and the sheet during use to prevent dust and debris from clogging the points of the abrasive and reduce air-borne dust, while producing a faster cut at the same time. These versatile sheets are ideal on surfaces that tend to generate a lot of dust, such as paint and primer; and can also be used dry for finishing metal and gel coats. In the marine industry they are used for sanding old finishes, fine feather edging, and surface work. The standard 9 inch x 11 inch sheets can be cut to size for the application.

Silicon carbide is a very hard mineral characterized by sharp points that fracture easily, resulting in freshly exposed sharp edges that cut extra fast and produce a smooth, professional-looking finish. Silicon carbide products are commonly used for low-pressure applications such as paint prep and finishing on wood and metal. While the mineral has a shorter life than aluminum oxide, it produces a superior finish.

Our 3M Wetordry products are backed with our proprietary waterproof paper backing that supports both wet and dry applications. Lighter weight than cloth and smooth rather than textured, paper backing is preferable for lighter applications such as finishing and paint prep. At the same time, many such applications produce a significant amount of dust, clogging the abrasive points and creating an inferior work environment. These effects can be minimized by sanding with water to rinse dust away from the workpiece and the abrasive surface.

Trusted 3M Wetordry Quality

The 3M Wetordry Paper Sheet 431Q offers reliable performance with a strong C-weight paper backing. This backing ensures durability whether you’re sanding by hand or using a machine, making it a dependable choice for various tasks.

Known for its quality, the 431Q model features silicon carbide mineral that produces a smoother finish than aluminum oxide. This makes it ideal for finishing work where a professional look is important.

Precise 9 Inch Dimensions

Each sheet measures 9 inches by 11 inches, a standard size that fits many sanding applications. The sheets can also be cut to size, allowing you to customize them according to your specific project needs.

This size versatility makes the 3M Wetordry Paper Sheet 431Q suitable for a variety of surfaces, including paint, primer, gel coat, metal, and wood finishes, providing flexibility in use.

Effective Wet Dry Use

The waterproof backing on these sheets supports both wet and dry sanding applications. Using water helps reduce dust buildup and keeps the abrasive surface clean, which leads to a faster cut and smoother finish.

Wet sanding is especially useful on surfaces that generate a lot of dust, such as paint and primer. This feature helps maintain a cleaner work environment and improves sanding efficiency.

Convenient 50 Sheet Packs

These sheets come in packs of 50, with 250 sheets per case, providing ample supply for multiple projects. This pack size is convenient for professionals and hobbyists alike, ensuring you have enough material on hand.

Having a large quantity available reduces the need for frequent reordering and supports continuous work without interruption, making it practical for busy workshops.

Versatile Silicon Carbide Abrasive

The silicon carbide mineral used in the 431Q sheets is known for its sharp points that fracture easily, exposing fresh edges for extra-fast cutting. This results in a smooth, professional finish on various materials.

While silicon carbide has a shorter life than aluminum oxide, it excels in low-pressure applications like paint prep and finishing on wood and metal, making it a versatile choice for many tasks.
